I was helping out a realtive with his bathroom project Thanksgiving weekend. I laid a field of diagonal 12" tile in the 30 sqft room, leaving him with the grouting, which he didn't appear to have any fear of. He picked up spectralok and apparently was overconfident of his ability.
Visiting on Christmas, I found that he had a visible spectrlock haze from a lack of good grout cleanup. He is a nice guy and generously gives me credit for helping him, but of course the finishing is less than desirable. What's the best way to get rid of the haze without replaceing the Porcelin tile?
TIA,
